Leners 'Param No. 90,161, dated Mag/18,1869.

fiMPncvnD RAmWAY-caam.

, 4The `Schedule referred to in these Letters Patent and makngpart of the sarna.-

side. to receive the contiguous ends of two rails, which are notched out on their'upperjedge, so that when the chair is in placethere shall beatread of the latter in continuation with thetre'ad of the rails, the chair having vertical-slottedwings through which a plate-key is passed and tigbtenedby means of a `vertical springkcy, the said plate-key coming beneatlrthe chair and theendsof the rails, and the chair being also provided with flanges o'n,each side of the vertical wings, which are bolted to cross-ties in the usual manner.

The construction and arrangement of the improved chair with the rails will; be understood bythe following description. l v. ,4

In the accompanying drawingsl Figure 1 is a" plan of the improved chair in connection with two rails. Y

Figure 2 isla cross-sectionof the same at the line :c :c of tig. 1.

Figure 3 is an isometrical view of the ke'y E.

Like letters in all the figures indicate the same parts.

A is the improved chair, and

B B, the contiguous nds of two rails.

' O O are cross-ties, to which the rails and chair are confined.

The chair A has a longitudinal groove, a, throughout its whole length, which ts over the projections b b of the rails B B, which are formed by notching out the ends of the same equal in depth to the thickness of the metal of the chair,`so that when the latter and the rails are in connection, there shall be an even and continuoustread. i

lhhe chair has vertical wings D D, which have hori- A zoutal slots, c, to receive the key E, by means of which the chair and rails are firmly held together.

I `usually make the chair of wrought-iron, and form the wings D D, by making slits, 1 2, equal to the depth of the wings, and bending them perpendicular tc the base il, at the same operation in which I bring the other parts of the chair-.into the finished form.

The key E, which is represented in detail iu fig. 3, has

holes e in two rows, alternating with each other to give., greater accuracy in the tightening'of the partsthe variations of the degrees of tightness being less in changing the spring-key F from, one row to the other than it would be with only asingle row, in consequence of this arrangement.

The chair is confined to the cross-ties C by means of the spikes j, which pass through the anges G G l What I vclaim as my invention, and desire to secure by LettersPatent, is- ,y l

The combination and arrangement of the railroadchair A, having a slot, a, vertical wings D, and flanges G, the plate-key E, and spring-key F, with the rails B,

`substantially as described.

In testimony that the above is my invention, I have hereunto set my hand and aiixed my seal, this 23d day of July, 1868.
